OK, Using the Beta-2020-04-05-00-19321 version I now have scroll bars on desktop 2 & 3. Thanks.

I also see the person number in the About section. I guess I'm just blind. LOL.

Thanks once again!

@ DJ Sures Progression from EZB srcipts to ARC scripts progressing very well, and I'm learning too. But back to arrays. I'm still stuck. Creating and accessing array within an ARC script, no problem: Pixel = ["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"];

_count = 0; while(_count < 16) { print("count = " + _count); print("Pixel = " + Pixel[_count]); _count++; }

But  I need to create the array in Init ARC script, and access the elements in another ARC script (global variable). But when I try to define with the same way as I do for global variables with the setVar(), I get: <<Variable is an array: $Pixel>>   and $Pixel is not shown in the global variable list i(t is not defined) Init script: setVar("$Pixel",["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"]);

How to define the arrays ?

Oh - I see... You want to push an array from JavaScript to the global variable. You're right, it seems to be not working. I just fixed it now and will publish it in tomorrow's beta channel for ya

Oh, btw... you can get the length of an Array in JavaScript with .length... like this...

Pixel = ["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"];

_count = 0;

while(_count < Pixel.length)
{
print("count = " + _count);
print("Pixel = " + Pixel[_count]);
_count++;
}

or you can simply loop through like this...

Pixel = ["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"];

for (int i = 0; i < Pixel.length; i++) {

  print("Pixel = " + Pixel[i]);
}

@DJ Sure Thanks. The global variable array definition works (They show up in the global variable listing) setVar("$Pixel",["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"]); But for some reason, I can not use a variable as an index to retrieve an element. This is ok: print(getVar("$Pixel[15]") ); But this does not work ( I get: << Input string was not in a correct format. >> _count = 0; x = getVar("$Pixel[_count]");

Same thing with a local script: << Input string was not in a correct format. >> _count = 0; x = getVar("Pixel[_count]");

Also, I can not get the .length to work.  setVar("$Pixel",["P0","P1","P2","P3","P4","P5","P6","P7","P8","P9","P10","P11","P12","P13","P14","P15"]); print(getVar("Pixel".length) ); That gives me << Variable not defined: $5 >>

cool

Assign the global variable to a local one.

var myArray = getVar($globalArray);

and then do stuff to that array

It says I have 2020 4.7 beta , a later version

@DJ Sures Yooohooo, it works !!! It took me a while to figure out a syntax error, but I'm not about to gorget it now (hope not). When retrieving elements from the array in the loop, I was coding getVar("$Pixel[_count]"); instead of getVar("$Pixel[" + _count + "]"); Now that I have control over the individual pixels of my Neo-Pixel Ring, I got to figure out how to write to the serial port. In EZB scripting, I was writing: $NeoPixelSerialPin = "0.d18" // Define serial pin (init script) SendSerial($NeoPixelSerialPin,9600,"C0,0,0") // Send string "C0,0,0" to serial port at 9600 baud But now, I assume I must use the COM.  So just open port and send data ? Open port: com.open(port, baud); COM.open(???, 9600); Send data: com.writeString(port, str); COM.writeString(???, "C0,0,0"); Am I close ? What do I write for port ?
